The name Palaeoptera (from Greek παλαιός (palaiós 'old') + πτερόν (pterón 'wing')) has been traditionally applied to those ancestral groups of winged insects (most of them extinct) that lacked the ability to fold the wings back over the abdomen as characterizes the Neoptera. The Diaphanopterodea, which are palaeopteran insects ...
Odonatoptera. Reconstruction of Carboniferous griffinfly, Meganeurites. The Odonatoptera are a superorder (sometimes treated as an order) of ancient winged insects, placed in the probably paraphyletic group Palaeoptera. The dragonflies and damselflies are the only living members of this group, which was far more diverse in the late Paleozoic ...
Mayflies (also known as shadflies or fishflies in Canada and the upper Midwestern United States, as Canadian soldiers in the American Great Lakes region, [2] and as up-winged flies in the United Kingdom) are aquatic insects belonging to the order Ephemeroptera. This order is part of an ancient group of insects termed the Palaeoptera, which also ...
Palaeoptera. Articles relating to the Palaeoptera, ancestral groups of winged insects (most of them extinct) that lacked the ability to fold the wings back over the abdomen as characterizes the Neoptera. The Diaphanopterodea, which are palaeopteran insects, had independently and uniquely evolved a different wing-folding mechanism. Both mayflies ...
The Pterygota / ˌ t ɛ r ə ˈ ɡ oʊ t ə / terrə-GOH-tə [3] (Ancient Greek: πτερυγωτός, romanized: pterugōtós, lit. 'winged') are a subclass of insects that includes all winged insects and the orders that are secondarily wingless (that is, insect groups whose ancestors once had wings but that have lost them as a result of subsequent evolution).
Neoptera (Ancient Greek néos ("new") + pterón ("wing")) is a classification group that includes most orders of the winged insects, specifically those that can flex their wings over their abdomens. This is in contrast with the more basal orders of winged insects (the "Palaeoptera" assemblage), which are unable to flex their wings in this way.
Another distinctive feature was the presence of unusually long cerci, about twice the length of the abdomen. [5] The Palaeodictyoptera are a paraphyletic assemblage of basal palaeodictyopteroidean insects, rather than a clade, because they gave rise to other insect orders. They range in time from the Middle Carboniferous (late Serpukhovian or ...
